From: Arınç ÜNAL <arinc.unal@arinc9.com>
For the switch on the MT7988 SoC, the code in mac_port_config for MT7988 is not needed as the interface of the CPU port is already handled on mt7988_mac_port_get_caps().
Make .mac_port_config optional. Before calling priv->info->mac_port_config(), if there's no mac_port_config member in the priv->info table, exit mt753x_mac_config() successfully.
Remove mac_port_config from the sanity check as the sanity check requires a pointer to a mac_port_config function to be non-NULL. This will fail for MT7988 as mac_port_config won't be a member of its info table.
